CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of and priority to Indian Patent Application No. 20222103921, filed on Jul. 7, 2022, the entire contents of which are incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present disclosure relates to woven sheets, more particularly to fitted sheets having a woven fabric top cover to cover the top surface of a mattress and drop area for fitting around all the four sides and corners of the mattress.

BACKGROUND

The textile industry is a major employment provider and revenue generator globally. Recently, the textile industry has achieved several technological advancements, and has adopted to environmental-safe operational procedures. Moreover, the textile industry is further evolving with improved durability for fabrics having global acceptability.

Conventional fitted sheets have a woven fabric top cover to cover the top surface of a mattress and drop area for fitting around all the four sides and corners of the mattress. These conventional woven sheets are normally made of either natural fiber or natural fiber blends or manmade fibers or manmade fiber blends or any combination thereof. However the comfort and the elegant look in the woven sheets are much higher for the sheets made with 100% natural fiber or natural fiber blends as compared to sheets manufactured using manmade fibers. Hence customers and users of the sheets preferred natural fabric woven sheets.

There are various patented fitted sheets such as U.S. Pat. No. 7,398,570 which discloses a fitted mattress cover in which a top panel of material for fitting in overlaying relationship to the top surface of a mattress and a peripheral skirt depending from the periphery of the top panel for fitting in overlaying relationship to the sides and ends of the mattress. The peripheral skirt comprises: a pair of extension sidewall panels attached to the top panel, said sidewall panels being sized and configured to overlie substantially the entire sides of the mattress; a pair of extension end panels attached to the top panel, at least one of said end extension end panels being sized and configured to overlie substantially only an upper partial portion of the end walls of the mattress; and at least one stretch end panel sized and configured to overlie substantially only a lower partial portion of a respective end wall below the upper partial portion. The stretch end panel is formed of a stretchable material stretchable in at least a longitudinal direction thereof so as to generate at least partial recovery force. The stretch end panel is attached along its upper edge thereof to a corresponding peripheral edge of a corresponding one of the extension end panels and being attached at its ends, either directly or indirectly, to corresponding end edges of the sidewall panels. Upon installation of the mattress covering, the at least partial recovery force pulls on said end edges of the sidewall panels.

U.S. Patent Application Pub. No. 20050193490 discloses a mattress pad having a central rectangular panel comprising a plurality of layers including an upper textile layer, a lower textile layer, and a batting layer quilted to at least one of the upper and lower textile layers. It includes side panels depending from said central panel and comprising a single layer of a textile fabric. End panels are defined by extensions of the central panel. The side panels being joined to the end panels by seams extending in a transverse direction in relation to said rectangular central panel. To fit the woven sheet over the mattress, the drop area of the sheets inserted under the mattress and above a hard surface such as wooden or metal bed or the floor as the case may be. Due to this exercise to fit the woven sheet, the drop area experienced more wear and tear as compared to the top cover. The wear and tear are likely to rupture of the drop area. The durability of natural fiber sheets are also quite low as compared to manmade fiber sheets. Moreover these sheets would consume more energy to dry due to higher moisture regain of natural fiber. The above-mentioned patent does not address these problems.

Recent advancements in manufacturing of durable woven sheets involves high thread count sheets. However conventional high thread count sheets require more raw material and more manufacturing requirements such as electricity, machines and man power which result into the higher cost. Naturally the cost of the high thread count woven sheet will also increase. Furthermore, conventional natural fabrics, which may be low or high thread count woven sheets, will have longer drying times. This will result in further increase in energy consumption as required for the sheets made of natural fibers.

Therefore, in light of the foregoing discussion, there exists a real need to overcome the aforementioned drawbacks associated with the conventional woven sheet. The present invention has a particularly advantageous application to sustainable, economic, quick dry and durable fitted bed sheets.

Furthermore each component shown in FIGS. 1-11 , e.g. the elastic bands, piping, pleats, T-shaped elastic bands, may be used in combination with each other as needed.

The yarn configurations described in the present disclosure can have several different structures. In one embodiment, the yarn configuration is a staple spun yarn formed from single end and/or multi ply yarns. Each staple spun yarn has a length and a plurality of single-ply staple spun yarns or multi-ply staple spun yarns twisted together. In another embodiment, the staple yarn could be made of 100% natural fiber. In yet another embodiment, the staple yarn could be made of 100% natural fiber blends. In another embodiment, the staple yarn could be made of 100% manmade staple fiber. In yet another embodiment, the staple yarn could be made of 100% manmade staple fiber blends. In another embodiment, the staple yarn could be made of natural fiber or natural fiber blends and manmade staple fibers or manmade staple fibers blends or any combination thereof. In another embodiment, the yarn configuration is a filament yarn. A filament yarn is made of one or more continuous filament strands with each component filament running the whole length of the yarn. Monofilament yarns are the yarns composed of one single filament, and more than one filaments are multifilament yarns.

The flat fabric as described herein may be defined by a number of different woven structures or woven design repeats. Depending on the particular design, woven design repeats may repeat along weft direction and warp direction; or both weft direction and warp directions. However, the design of the woven fabric is not limited to any particular weave structure. For example, the woven fabric can have a number of exemplary woven structures including, but are not limited to: plain weaves; basket weaves, rib weaves (e.g. 2×1 rib weave; 2×2 rib weave; or 3×1 rib weave); twill weaves; oxford weaves; percale weaves, satin weaves (e.g. satin dobby base, satin stripe satin 5/1, satin 4/1 satin; 4/1 satin base strip; 4/1 stain swiss dot; 4/1 down jacquard; 5/1 satins), or sateen weaves. In one example, the woven fabric is a plain weave. In another example, the woven fabric is a basket weave. In another example, the woven fabric is a rib weave. In another example, the woven fabric is a twill. In another example, the woven fabric is an oxford weave. In another example, the woven fabric is a sateen weave. In another example, the woven fabric is any other possible weave structure. In another example, the woven fabric is a satin weave. Furthermore, a number of exemplary satin constructions are possible. For instance, in one satin weave example, the woven fabric is a 4/1 satin. In another example, the woven fabric is a 4/1 satin dobby diamond weave. In another example, the woven fabric is a 4/1 satin dobby stripe. In yet another example, the woven fabric is a 4/1 satin jacquard weave. In another example, the woven fabric is a 5/1 satin. In still another example, the woven fabric may be a 6/1 satin. In another example, the woven fabric is a 7/1 satin. In yet another example, the woven fabric is a 8/1 satin. In another example, the woven fabric is a 9/1 satin. And in another example, the woven fabric is a 10/1 satin.

The present disclosure can utilize co-insertion techniques to insert multiple weft yarns along a weft insertion path in a single weft insertion event during weaving, as will be further detailed below. A person of skill in the art will appreciate that the weft insertion path varies from one woven design to another woven design. By inserting groups of multiple weft yarns into the shed during a weft insertion event, it is possible to attain increased weft (or pick or fill) densities and therefore higher thread counts. Thus, the woven fabric as described herein may be constructed to have higher weft yarn densities than what is otherwise possible, and thus higher thread counts, yet the woven fabric exhibits desirable fabric quality, softness, hand, and drape suitable for bedding applications. The thread count of the woven fabrics made in accordance with present disclosure are typically greater than about 100 and can be as high as about 2000 (or even higher). The thread count as used herein is the total number of yarns in square inch of fabric. The thread count in this context is based on total number of yarn ends. In other words, plied yarns are considered one yarn for the purpose of determining thread count.

The present disclosure can utilize co-insertion techniques to insert multiple weft yarn along a weft insertion path in a single weft insertion event during weaving, as will be further detailed below. A “co-insertion” technique is where multiple pick or weft yarns are inserted into the warp shed at one time during weaving. In co-insertion, two pick yarns supplied from two different yarn packages are inserted at one time through the shed during weaving. Co-insertion may also include inserting three or more yarns supplied from the three or more different yarn packages into the shed during weaving. In one example, the woven fabric has between one (1) weft yarn and seven (7) weft yarns inserted during a single insertion event, i.e. along the weft insertion path.

The warp yarns and weft yarns are arranged to achieve desired warp and weft end densities, respectively, and thus desired thread count, for bedding applications. In accordance with an embodiment of the present disclosure, the woven fabric has a warp end density between about 50 warp ends per inch and about 550 warp ends per inch. In one example, the warp end density is between about 50 and 150 warp ends per inch. In another example, the warp end density is between about 150 and 250 warp ends per inch. In another example, the warp end density is between about 250 and 350 warp ends per inch. In another example, the warp end density is between about 350 and 450 warp ends per inch. In another example, the warp end density is between about 450 and 550 warp ends per inch. Furthermore, the weft yarns are arranged to define a weft end density between about 50 weft yarns per inch and about 1500 weft yarns per inch (or more). In one example, the weft yarn density is between about 100 and about 1500 weft yarns per inch. In one example, the weft yarn density is between about 100 and about 300 weft yarns per inch. In another example, the weft yarn density is between about 300 and about 500 weft yarns per inch. In another example, the weft yarn density is between about 500 and about 700 weft yarns per inch. In another example, the weft yarn density is between about 700 and about 900 weft yarns per inch. In another example, the weft yarn density is between about 900 and about 1100 weft yarns per inch. In another example, the weft yarn density is between about 1100 and about 1300 weft yarns per inch. In another example, the weft yarn density is between about 1300 and about 1500 weft yarns per inch. The weft yarn density has used herein refers to the total number of separate weft yarns along a length of the woven fabric. For example, a weft yarn density of about 50 picks per inch refers the 50 total weft yarns per inch of woven fabric. If the weft yarn groups are inserted during a single weft insertion event and each group includes three (3) weft yarns, then there would be about 16 total weft yarn groups per inch of fabric and 48 picks per inch.

The yarns can have a range of counts for the different fibers and woven constructions as described herein. The yarn count as used in this paragraph refers to the yarn count for each single end yarn and the yarn count of the multi-ply yarn. The yarn count can range between about 8 Ne (664 denier) to about 140 Ne (37.9 denier). In one example, the yarns can have a count in a range between about 8 Ne (664 denier). In one example, the yarns can have a count in a range between about 20 Ne (266 denier). In one example, the yarns can have a count in a range between about Ne (177 denier). In one example, the yarns can have count in a range between about 40 Ne (133 denier). In another example, the yarns have a count of about 60 Ne (88.6 denier). In another example, the yarns have a count of about 70 Ne (75.9 denier). In another example, the yarns have a count of about 80 Ne (66.4 denier). In another example, the yarns have a count of about 100 Ne (53.1 denier). In another example, the yarns have a count of about 120 Ne (44.3 denier). For flat woven fabrics, the warp yarn counts may range from 20 Ne (266 denier) to about 100 Ne (53.1 denier). The weft yarn counts may range from 20 Ne (266 denier) to about 140 Ne (37.9 denier).

The flat fabric can use different yarn constructions in the warp and weft components. In one example, the warp yarns are typical staple spun yarns (cotton or any fiber blends natural and manmade fibers or 100% manmade fibers) and the weft yarns include single ply or multi-ply staple spun yarns of any fiber blends natural and manmade fibers or 100% manmade fibers. In one example, the warp yarns are typical continuous filament yarns and the weft yarns are single ply yarns or multi-ply staple spun yarns. In another example, the weft yarns are typical staple spun yarns and the warp yarns are single ply yarns or multi-ply staple spun yarns. In one example, the weft yarns are typical continuous filament yarns and the warp yarns are single ply yarns or a multi-ply staple spun yarns. In one preferred embodiment, the warp yarns are typical staple spun yarns and the weft yarns include single ply or multi-ply staple spun yarns. In one preferred embodiment, the warp yarns are typical staple spun yarns and the weft yarns include filament yarn.

The staple fibers may be cotton fiber. Alternatively, for example, in place of cotton, may contain viscose fiber, modal fiber, kapok fiber, raime fiber, hemp fiber, nettle fiber, silk fiber, linen fiber, bamboo fiber, acrylic fiber, polyethylene terephthalate (PET) fiber, polyamide fiber, or blends of fibers or a bi-component fiber, charcoal fiber, PLA fiber. Fiber blends, for example, may include, but are not limited to: cotton and viscose fiber blends; cotton and modal fiber blends; cotton and silk fiber blends; cotton and modal fiber blends, cotton and linen fiber blends; cotton and bamboo fiber blends; cotton and acrylic fiber blends; cotton and PET fiber blends; cotton and polyamide fiber blends; viscose and modal fiber blends; viscose and silk fiber blends; viscose and modal fiber blends, viscose and linen fiber blends; viscose and bamboo fiber blends; viscose and acrylic fiber blends; viscose and PET fiber blends; viscose and polyamide fiber blends; PET and viscose fiber blends; PET and modal fiber blends; PET and silk fiber blends; PET and modal fibers, PET and linen fiber blends; PET and bamboo fiber blends; PET and acrylic fiber blends; and PET and polyamide fiber blends. Or any other possible combinations. The PET fiber as described in the current disclosure may result from PET chips. In one example, the PET chips may be PET could be dull. In another example, the PET chips may be PET could be semi dull. In another example, the PET chips may be PET could be bright. In another example, the PET chips may be PET could be full bright.

The PET fiber as described in the current disclosure may have circular cross-section (CCS). Alternately, for example, in place of circular cross-section fiber of any non-circular cross-section (NCCS) could be used. In one example, the cross-section could be oval shape. In another example cross-section could be tri-lobal. In another example, the cross-section could be quadrilobe shape. In another example, the cross-section could be pentalobal. In another example, the cross-section could be octalobal. In another example, the cross-section could be multilobal. In another example, the cross-section could be delta. In another example, the cross-section could be cross.

In one preferred embodiment, top area is a flat fabric manufactured using typical staple spun yarns (cotton or any fiber blends natural fibers) and drop area is a flat fabric manufactured using mono filament or multi filament yarns or staple spun yarns of any fiber blends of manmade fibers. In order to achieve similar look and feel to the top area, the non-circular cross-section (NCCS) man-made fibers may be used in the second flat woven fabric, used for the drop area. In one example, the NCCS man-made fibers may be PET fibers. More specifically use of quadrilobe cross section PET fiber may be used as the manmade fibers in the drop area. The PET filament yarn count may range from 10 denier to about 300 denier. In an embodiment, the PET filament yarn count range is 10 denier to 30 denier. Yet another embodiment, the PET filament yarn count range is 30 denier to 75 denier. Yet another embodiment, the PET filament yarn count range is 75 denier to 150 denier. Yet another embodiment, the PET filament yarn count range is 150 denier to 300 denier.

As a first step, yarn formation of natural fibers (or cotton fibers) are subject to an opening step in a blow room. In the blow room, the cotton fibers are processed with a bale plucker, opener, multi-mixer, beater and a dustex machine. After opening, the fibers are carded on card machines to deliver card slivers. The sliver from carding is then processed through a breaker drawing step to draw out the slivers. In one example of the breaker drawing step, the number of doublings at the feed end can be 6 and the hank delivered is maintained at about 0.10 to 0.13. In case of blended slivers, each component is separately processed through carding and the individual carded slivers are subsequently blended together on draw frames. From breaker drawing, the slivers can follow one of two processing steps: a lapping step or fed directly roving step.

In instances where combing is needed, processing proceeds from the breaker drawing to the lapping step. As should be appreciated, combing is used to remove short fibers during cotton processing. In the lapping step, a unilap machine converts doublings into a lap of fibers. The lap is processed in a combing step using a comber. The combed cotton sliver is then passed through another finisher drawing step to obtain sliver which can be used as input of roving frame. In one example, the finisher draw frame has a feed hank in the range of 0.10 to 0.13 and a delivery hank in the range of 0.65 to 2.5 and at speeds up to about 400 meters per minute.

Referring back to step, in certain instances, the slivers produced at breaker drawing step are fed to finisher drawing and then directly to the roving step, further explained below.

As a next step, the sliver is fed to the speed frame which includes an inlet condenser, a middle condenser, a main feed condenser, multiple sets of drafting rollers, and a flyer. Typically, slivers are processed through an inlet zone, back drafting zone, middle drafting zone, and a forward drafting zone. The condensers are disposed along these different zones at or near their respective drafting rollers. The cotton sliver follows a normal path from the back to the front of the speed frame through at least the main feed condenser. The twisting and winding on to the bobbin on the speed frame is typical as with any other cotton roving system. For example, clockwise rotation of the flyer can give “Z” twist. Alternatively, the roving can have an “S” twist, by reversing the direction of the rotation of the flyer to a counter-clockwise direction. The roving hank ranges from about 0.5 to about 2.5 hanks. In one example, the hank of roving can be about 0.58. In yet another example, the hank of roving can be about 1.00.

After the roving step, a yarn spinning step converts the roving into single end yarn. In accordance with illustrated embodiment, yarn spinning is accomplished on a ring spinning system using typical settings for forming ring spun yarns. The spinning parameters on the ring spinning system are set based on the type of fibers in the overall yarn structure. The ring spinning frame can produce single end yarns with a count that ranges from about 8 Ne (664 denier) to about 140 Ne (37.9 denier). Yarns used for flat woven fabric may have a count that ranges from Ne to about 120 Ne (44.3 denier).

Yarn spinning is also accomplished on a rotor spinning system using typical settings for forming open end yarns. The spinning parameters on the rotor spinning system are set based on the type of fibers in the overall yarn structure. The rotor spinning system can produce single open end yarns.

Yarn spinning is also accomplished on a friction spinning system using typical settings for forming single end yarns. The spinning parameters on the friction spinning system are set based on the type of fibers in the overall yarn structure. The friction spinning system can produce single end yarns.

Yarn spinning is also accomplished on a self-twist spinning system using typical settings for forming single end yarns. The spinning parameters on the self-twist spinning system are set based on the type of fibers in the overall yarn structure. The self-twist spinning system can produce single end yarns.

Yarn spinning is also accomplished on an electro-static spinning system using typical settings for forming single end yarns. The spinning parameters on the electro-static spinning system are set based on the type of fibers in the overall yarn structure. The electro-static spinning system can produce single end yarns.

Yarn spinning is also accomplished on a vortex spinning system using typical settings for forming single end yarns. The spinning parameters on the vortex spinning system are set based on the type of fibers in the overall yarn structure. The vortex spinning system can produce single end yarns.

Yarn spinning is also accomplished on an air jet spinning system using typical settings for forming single end yarns. The spinning parameters on the air jet spinning system are set based on the type of fibers in the overall yarn structure. The air jet spinning system can produce single end yarns.

Yarn spinning is also accomplished on a twist less spinning system using typical settings for forming single end yarns. The spinning parameters on the twist less spinning system are set based on the type of fibers in the overall yarn structure. The twist less spinning system can produce single end yarns.

After yarn spinning, the yarn is further packaged into suitable yarn packages using auto-corners. Those packages are then used in a plying step for making multi ply yarn wherever required. In plying step, the yarns plied into multi ply yarn. In accordance with the illustrated embodiment, the plying step uses two-for-one twisters to twist two single end yarns into a two-ply yarn. Accordingly, as shown, the intermediate plied staple yarn is a two-ply yarn that includes a first staple yarn and a second staple yarn twisted with the first staple yarn to define the plied yarn. The intermediate plied yarn can have an overall twist per inch (TPI) from about 3.5 to about 14.5 TPI in an “S” direction. The twist direction can, however, be in a “Z” direction. Furthermore, the twist configuration can be either Z over S or Z over Z. The resultant yarn counts would be from about 2/10s to about 2/120s. In alternative embodiments, the intermediate plied yarn can be 3-ply yarn. Such a 3-ply intermediate yarn includes a first staple yarn, a second staple yarn, and a third staple yarn twisted into a plied structure. More plies than 3 can be used as needed. After yarn plying, the plied yarns are wound onto suitable yarn packages for further processing. For example, the plied yarn can be cross-wound onto a yarn package.

As a next step, the plied yarns proceed to a warping step. The warping step includes typical warping operations for flat woven fabrics.

A weaving step follows warping. The weaving step converts the yarns into woven fabrics. One or more looms, e.g. projectile, air-jet looms, rapier looms, water-jet looms (or others) can be used during the weaving step. Each loom may utilize typical shedding mechanism, such as a cam, dobby or jacquard type shedding mechanism. During the weaving step for the woven fabric 1, the warp and weft yarns can be arranged into a number of different weaving constructions and designs as is known by persons of skill in the art and that detailed above. For instance, the flat woven fabrics may include a plain weave, twills, rib weaves, basket weaves, percale, satins, sateens, other woven designs. In accordance with an embodiment of the present disclosure, the weaving step forms a woven fabric to have a) a warp end density between about 50 warp ends per inch and about 550 warp ends per inch; and b) a weft end density between about 50 weft yarns per inch and about 1500 weft yarns per inch (or more). In one example, the weft yarn density is between about 100 and about 1500 weft yarns per inch. Furthermore, the flat woven fabrics may have thread counts ranging from 100 TC to about 2000 T C. The weaving step may include co-insertion or insertion of multiple picks during a single pick insertion event. In one example, the weaving step includes inserting between one (1) weft yarn and seven (7) weft yarns during a single insertion event along the weft insertion path. Furthermore, for woven fabrics, the weft yarns, warp yarns, or both the warp and weft yarns can include the staple spun yarn or filament yarn. The flat woven fabrics are formed to have constructions that are suitable for bedding applications in both consumer, hospitality and/or healthcare markets.

The weaving step results in “greige fabrics” that are further processed into textile articles. After the weaving step, the greige fabrics are inspected. Following inspection, the natural as well as synthetic fabrics can either undergo a batch dyeing or a continuous dyeing.

The batch dyeing includes pretreatment namely desizing, scouring, bleaching, and dyeing; dyed in a typical fashion in a fabric dyeing machine. The operating temperature is maintained in a range from about 50° C. to about 120° C. The operating temperature for natural fabrics is maintained in a range from about 50° C. to about 80° C. The operating temperature for manmade fabrics is maintained in a range from about 95° C. to about 120° C. Batch dyeing may follow high temperature high pressure (HTHP) dyeing to make color the PET part. The operating temperature for natural and manmade fabrics blend is maintained at its respective temperature and condition as captured herein before. The batch dyeing step utilizes a liquor ratio sufficient to facilitate the overall process, and allow is free movement of the fabric in the dyeing machine. The liquor ratio may range from about 1:5 to about 1:30. For example, the liquor ratio may be 1:5, 1:10, 1:12, 1:15, 1:20, 1:25, 1:22, or 1:28.

During batch dyeing step, the fabrics are typically wound into the shape of a rope prior to entering the fabric-dyeing machine. The rotation of the fabric in rope form aids in uniform pretreatment and dyeing. Finishing is an optional step may be used to apply any specialty chemicals if required. After pretreatment and dyeing operation is over the fabric can be rinsed and neutralized and followed by unloading from the dyeing vessel. After unloading the woven fabrics from the vessel, the water is extracted material in an extractor in the typical manner to reduce the moisture content from 200% to 60%. A rope is passed through rope opener, which is equipped with drumbeaters both at feed and delivery ends, to straighten the twist in the rope. Then the material is passed two times through a hot air dryer which is equipped with drumbeaters at both the feed and delivery ends. This ensures proper lifting of the pile. The first drying is carried out at about 120° C. The second drying occurs at a higher temperature, such as 150° C. for about 4 minutes to about 5 minutes. The full width fabric is then passed through hot air stenter and a weft straightener to straighten the fabric and return it to its proper dimensions.

As described above, after the inspection step, the greige fabric can processed using continuous dyeing range in a continuous dyeing step using process temperature and conditions as applicable to respective fiber or blends. After the continuous dyeing step the woven fabric is dried. The drying step utilizes a hot air dryer to further dry the fabrics at the desired temperature. The dried fabric is expanded to full width and then passed through a stentering step. The stentering step can help straighten the fabric. Finishing is an optional step may be used to apply any specialty chemicals if required.

Following the stentering step (or optional shearing step), a cutting step cuts the woven fabrics to the desired length and width depending on the particular end use.

For flat woven fabrics, after cutting, the cut woven fabric is stitched.
